Outcome: Genetics and the Environment

Discuss the role environment plays on phenotypes.

In recent years, scientists have begun to research how our environment can impact our phenotypes. In this outcome, we’ll learn about a few different ways our environment can impact us.

What You’ll Learn to Do

  • Explain how epistasis impacts trait expression.
  • Describe polygenic inheritance and how to recognize it.
  • Describe continuous variation and how to recognize it.
  • Identify gene-environment interaction and how this impacts trait expression.
  • Explain pleiotropy and its impact on traits in a population.
